I have no defense, except that until I get to know someone really well, it's easier for me to be a normal, single guy. Because it's way too complicated to be who I really am. I'm a full-time dad. I'm a working parent. I'm a mother and a father. I'm a guy who reads parenting books and cookbooks before I go to sleep. I spend my weekends buying tutus. I'm learning to sew. I'm Mr. Napkin Head. I'm on some kind of constant overload and it helps to compartmentalize my life. Just till I figure this out.
And I suppose there's... the possibility I'm afraid of what another person might do to who we are and how we get from one day to the next.
